>http://www.cs.clemson.edu/~mark/stretch.html Missing a few key points: 1. Unlike the S/360 et al, Stretch did not have 8-bit bytes; it had bytes of the size specified by the programmer, and as I recall they could start at an arbitrary bit position and could straddle word boundaries. 2. The 7909 data channel on the 709x, and similar channels on the 1410, 7010, 704x, 707x and 7080, were spinoff's of the 7030's exchange and were the inspiration for the I/O architecture of the S/360. 3. Some peripheral equipment originally designed for Stretch became common on other boxen, in modified form. -- Shmuel (Seymour J.)
